Ultra High Molecular Weight Polyethylene (UHMW)
UHMW, also known as UHMW-PE (Ultra High Molecular Weight Polyethylene), is a semi-crystalline thermoplastic material, with a continuous use temperature range of up to 180° F (82° C).
UHMW, also known as UHMW-PE (Ultra High Molecular Weight Polyethylene), is a semi-crystalline thermoplastic material, with a continuous use temperature range of up to 180° F (82° C). It is categorized as an engineering material, and offers a unique combination of wear and corrosion resistance, a low-friction surface, and high impact strength.
UHMW exhibits very low moisture absorption, and retains key physical properties at temperatures as low as minus-22° F (minus-30° C). It offers very good electrical insulating properties, moderate mechanical strength and stiffness, and excellent machinability. It is an excellent general-purpose material which offers performance properties that make it effective in a tremendous range of applications, particularly food handling solutions, conveyance mechanisms and material handling, and packaging solutions where wear resistance and durability are crucial. Plus, UHMW meets a wide range of regulatory compliance standards, including 3-A Dairy, ASTM/Mil-Spec, FDA, UL-94 Flame Class, and USDA.
Polymershapes proudly offers UHMW from industry-leading manufacturers, including Quadrant Engineering Plastics, makers of Tivar®. We can meet your UHMW needs in a variety of shapes and sizes, including sheet, rod, and tube.
